The marine hydrometer for sea water has a range of 40, the degrees expressing the third decimal of specific gravity, i.e., 5 = 1.005 sp. gr.; 22 = 1.022 sp. gr.
The Brix hydrometer for sugar solutions is so graduated that 1 indicates 1 per cent of sugar in solution. The above table gives a comparison between it and the Bauni6 scale. In addition, if the specific gravity of a pure cane-sugar solution is known the above table will give the percentage of sugar in it.

Balling's hydrometer, much used by English dyers is so graduated that sp. gr. =   nnn  ,  _, the
sign being used if the liquid is lighter than water, the    sign when heavier. Balling0   =  (|5)Be;Be0 = ~ Balling0.
